FLEXIBLE UNDEREAVE.

Application filed m 27, 192a. scrim no. 654,172.

To all whom it may concern:

Be it known that I, ALBERT ABBn Giuswonn, a citizen of the United States, residing at Providence, in the county ofProvie dence and State of Rhode Island, have invented a new and useful Improvement in Flexible Undereaves, of which the following is a specification.

My invention has reference to an improveit) ment in. flexible shingles and more particularly to an improvement in flexible undereaves such as shown in United States Patent No. 1,321,624, granted to me November 11,

1919, for flexible undereave, and used-in con- 16 nection with flexible shingles, as shown in United States Patent No. 1,274,410, granted to me August 6, 1918.

In shingling a roof or the like with flexible shingles laid diagonally, I find that the roof or the like is greatly improved in corn struction and appearance and the first course in laying the shingles diagonally greatly facilitated by the use of my improved undereaves, which lie on the roof at the edge of the eaves and form the first course in shingling a roof or the like.

The object of my invention is to provide a flexible undereave for use in connection with the laying of flexible shingles in shingling a roof with the shingles laid diagonally, whereby the shingling of the roof is expedited and a more perfect root of its kind constructed, than has heretofore been done.

A further object of my invention is to improve the construction of such an undereave whereby a large portion of the material heretofore required in constructing the undereave is eliminated, thereby greatly re ducing the cost of manufacturing the undereave.

Another object of my invention is to construct such an undereave so that the undereave inthe blank form, is cut out of standard width stock, with, the least possible amount of waste.

My invention consists in the peculiar and novel construction of a flexible undereave having details'of construction, as will be more fully set forth hereinafter and claimed.

Figure 1 is a plan view of a portion of a flexible shingled roof, with the shingles laid diagonally and showing the same provided with my improved flexible undereaves.

Figure 2 is a plan view of my improved flexible undereave, looking at the face of the undereave.

Figure 3 is an end view of the undereave. Figure 4c is a lower edge view of the undereave, and

Figure 5 is a face plan view' of the under lower corner flap 9 with a wire 10 having outwardly extending side ends 11, 11 which go under the angular lower edges 12, 12 of shingles previously laid, to hold down the lower end of the shingle.

My improved flexible undereaves 8, 8 are formed preferably of the same material as the flexible shingles 7 7. Each undereave 8 consists of a preferably rectangular shaped flat body, the same width as a shingle 7 and half the height of a shingle 7 It is constructed to have a face 13 usually of ground slate, a back 1 1, a straight top edge 15, side edges 16, 16 at right angles to the top edge 15, a straight lower eave edge 17 merging at each side into an angular lower opening corner edge 18 which in turn merges into a short neck 19 on the side edges 16, 16, as shown in Figures 3, 4 and 5. On each neck 19, is a rectangular shaped turned under flap 20, all formed integral.

In shingling a roof or the like with my flexible shingles 7, 7 laid diagonally on the undereaves, the first course is formed by laying my improved flexible undereaves 8, 8 on the roof with the lower eave edges 17, 17 at the cave edge of the roof and secured to the roof at .21, 21, by nails, as shown in Figure 1. The shingles 7 7 are now laid by placing a" shingle over the adjacent end portions of two undereaves in aposition for the wire side ends 11, 11 to go under the adja cent angular lower corner edges 1:8, 18 of the undereaves. The shingle is then moved upwards and the wire. side ends 11, 11 go under the angular lower corner edges 18, 18 of the undereaves, thereby firmly securing the lower end of the shingle to two 'undereaves previously nailed to the root. The underturned lower corner fiep 9 on the shingle 7 now lies on the two adjacent underturned fieps 20, 20, of the undereeves and fits between the adjacent angular lower corner edges 18, 18 of the underenves, The shingle is now nailed through its side corners to the roof and the next and following courses of shingles are leid and secured in the same way. The undo-reeves 8, 8 have marks 22, 22, to indicate where the undereeves are to be nailed to the root.

In the construction of my improved flexible undereave e materiel saving in the cost of manufacture is obtained end such a flexible shingledroof is constructed, at less cost, than has heretofore been done.

Having thus described my invention 1 claim as new:--

1, A rectangular flexible undereeve having parallel top end bottom edges, parallel side edges, angular lower corner edges and underturned side flaps, for the purpose as described. l

2. A rectangular flexible undereave havteeoeo in parallel top and bottom edges, parallel si e edges, angular lower corner'edges and rectangular underturned side flaps, for the I purpose as described.

3. A rectangular flexible undereeve having top and bottom edges, side edges, angular lower corner edges, a neck on each side edge and an underturned flap on each neck, for the urpose as described.

4. A- exible undereave having top end bottom edges, side edges, angular lower eorner edges and en under-turned flap on each side edge, said underturned flaps lying under the angular lower corner edges, forthe purpose as described.

5; A flexible undereeve formed of e fibrous materiel end having e face of ground slate, at fibrous beck, parallel top and bottom edges, parallel side edges, angular lower corner edges and turned under side flaps which lie under the angular lower corner edges, for the purpose as described.

In testimony whereof, I have signed my name to this specification.

ALBERT ABBE GRISVVOLD.
